I have been placing epoxy in the panel joints of my Coho. The unthickened expoxy has bubbles entrained in the liquid. These are quite small, typically 1/16 to 1/8" in diameter. Looking at the joints you can see the resulting bubbles after the expoxy hardens. Some of these rise to the surface, and will be removed by a light sanding, while others are below wood level, and will remain forevermore. Three questions. 1) Is this a common problem or am I just looking too close? 2) How can I stop or minimize this from happening again? I would really like my deck to be clear of this problem. 3) Any input on if these bubbles will impact the integrity of the structure? They would be quite difficult to remove. Thank you for the help.
